To all whom 'it may conzem:

Beit known that I, GEoRGE F. FISHEIg-a .Y citizenof the United States, residing at Afwhichtheitollowing is a specification.

` North Tonawanda, in the county of Niagara and Stateof New York, have invented certanr new and useful' Improvements 1n Forms for Concrete Building Constructions, of

This invention relates to adjustable and sectional forms for concrete building constructions, and it has `for its primary object, the production of a form which can be used numerous times and: adjustedvto the required liable,

'size in all directions for various size columns, girders, walls,` anddother parts of buildings. Y .l

Further'. objects are, to provide simple, re-

and effective means to connect the `vvarious parts and sections of the form; to

provide'means for .leveling and supporting thegirder-sections of the form; and to oth.

erivise improve on forms for concrete build- A ing constructions non" m use.

To' tliesegends'the. invention consists in the construction, arrangement, and` combination of parts to be hereinafter described and particularly pointed'outin the appended claims.

The invention is illustrated lin the accompanying drawings, in which similainunierals and letters of reference refer to-simi- '.2 `is a broken sectional elevation ot' a part ot in v improved forni including interior column-forms and girder-forins receiving support from said column-forms. Fig. 3 is a plan view of a part ofthe forni including interior columnforms and girderforms supported thereon. Fig. 4 is a vertical see-- tion, taken on line u----u, Figi, looking to the left.

Fig. 1B an* en-l larged vertical section, taken on 'line s-s, Fig. 1. Fig. 14 is a cross-section, taken on line t-, Fig. 13. y

The reference letterdesignates the column-forms, B', the glider-forms, and C, a wall-forni. W Each column-torni comprises four" side plates 11 connected at the corners by' angle' bars 12 which extend from the door of tlie tonndationto the. floor next above, or from' the top of onefioor to the next floor above' or to the roof, as the case may be. The side plates are formed in sections 13 lia'yinothe end edges abutting, so that any height'- of column may be molded by .using the proper number of sections, or by using"I sections of different lengths tol foi'1n' tl1e1c0i"`- rect height for the side plates. ATheA angle bars 12 are likewise'fnlned inv sections abutting at the ends, but have their joints ori'- ditt'erent planes from those of the side plates, so` .that the plates and corner-bars'4 leach other; thus assuring a rigid construction when the plates are properly securedy in place.

The side plates may be bolted to theicorner angle-bars when adjustment in thickness of column is not desired; but I have herein shown a construction permittinga'djustinent oi vthe column-forni with respect to its width. This l preferably do by pro,- riding the.several'sections ot'fthe side plates with horizontal slots 14 at intervals in tlie length thereof through which extend' bolts 15 that are passed tbrough the angle-bars. Said bolts have'their heads counter-sunk into the angle-bars to provide an even interior surface and -their projecting ends are provided with nuts v16 to secure the platesto' the corner angle-bars.` By reason of this eonstrm-tion, colulnns of -different thick' ne-tsescan be .nolded; but it isiny intention to limit the ex'tent to which the .size of the column-imi' be raried. so that two o1' three sets of.l forms will be required to torni the ditlerent size columns non' in use in building-constructions. This l prefer for the reason that extension of the column-forms beyond certain limits, requirelargercorner have theirjoints broken with respect to" angle-bar sections. This is a very desirable feature of my invei'ition, as it assures a rigid and 'reliable connection between the varlous sections forming the height of the columnform.

AThe girder-forms B which are used t'o mold the girders for-the outer walls aswell as the bridging of interior columns, or in terior columns with wall columns, are also formed in sections so that any 'length of span between columns can be easily provided forby insertion or substitution of the proper lengths of sections; while provision is made l for adjusting the depth and Width of this portion ofthe' form to any desired extent 425 within certain limits, Each girder-form. comprises side-plates formed of sections 17 which abut at their ends, as at 18, with the exception of the center sections which lie within the adjoining sections, as at 19, best Ishown in Figs. 3 and 12, to allow a limited extension orcontraction inthe length of the l girder; bottom plates formed Vof sections 20 which also abut, with the exception of the center-section which lies with its ends on the adjoinin bottom plates, as at 21; and corner' ang e-bars formed in sections 'which form the longitudinal corners of the troughlike form for; the girders'. As shown in Fig.

' 12, short lengths of corner'angle-bars 22.a 40 are inserted between the ends of'the anglebars of the intermediate section and the ends of the angleebars of the adjoining sections, when extension of the girder-formis made,

so that the yform is closed at the angles throughout its lengthsmand an even finish given the molded ginder. In order that the depth of the girde'r to be cast may be varied on the diiierent floors, or on dill'crent buildings, thefside-plates are provided with vertical slots 23, nd 'bolts- 24 pass .throughthe vertical Webs of bars 22 from the inner side of the' form and extend .through saidslots, having applied to their. outer 4'proje cting ends, nuts 25 to .secure said parts together, and whereby vertical adjustmentsfof "*theg f''pletis ifftcledf ,The bottom* late-s" :eend fittasi-27' passed't rough'th'e' horizbntal webs trein outer projecting. ends', nuts-28 to seeure' said bottom plates to said corner-bars. The inner ends of lbolts 24 and 27 are'- geountersunk into the cornenbars to insure @smooth ,inner 'surface to the form.v vBy ymeans of the slots'26 and bolts 27, the Width 'of the form can be adjusted for different size girders, which are, as is well known, progressively narrower and of less depth, on the successive ioors of a building.

rl`he joints betweenthe'corner angle-bars 22 and thesides' and' bottom plates of the girder'-form are broken, as and in the 1nanner describedwith reference to the construction of -the column-forms; which assures a rigid and substantial connection between the sections forming the girder-forms, except as described in respect to the connection and manner of supporting the center section.

.As best shown in Figs. l, 2, and 4, the end plates 20 of the bottom of. the girder-form have connections with the adjacent 'sideplates of the column-forms by inclined `-plates 29gea-ch of which is bolted or riveted at one endto the end plate of the bottoni of the girder-forni by an angle strap 30, and at its other end fastened in like manner by an anglestrapBOa to 'the sides of the adjacent column-form. j t

"Where the girder-forms connect with the column-form, the `side plates of the latter terminate in a4 plane below the bottom of the A ,girder-orm "so that the inclined plates 29 may beconnected with the ends of bo't-h in orderto form the usual haunch'at the upper lends of the'columns; but as stated, the cor'- nerangle-bars 12 of the column-forms extend to the door line next 'abore which is also the top of the girder-.form. o

On the outer side-of thewtll column- Aforms there is no connection with a girdelrform, and consequently the'side plates are 'extended up to the upper ends of .the angle bars 112 at such places; Where connection is made between a girderform and a column-form, narrow extensions 31, (Fig. 11)' are provided for the sides of the column-form' which are 'narrow plates thatextend fronr the upper edge of the up# permost full width side plate' to' the top of the angle-bars' 12, two vsmall plates being provided on each side of the'column-form, each having horizontal slots 32v through which extend bolts 33 that are passed through the angle-bars 12 and haven'uts 34 threaded vonto their outer projecting ends to secure 'Suid plates to said angle-bars; this permits adjustment -of the narrow extensions' or plates to conform to theadjistment of the istitu-gine*interim-fe t necting` plates thatzlie between 4,the end ,sections of the ginder-'forms and said narrow barsv 36 riveted at 37 to theextensio'nsor plates .31 and the 'connecting plates 35L fgln rao'rmsfa l they are connecte with short and'wide concerner-bars. and' have4 threaded onto .The slots 32 in the' narrowside-plates 31 need lnot be aslongas the slots. 14 in the wide side plates, since 'u onincreasing or diminishing'the width o the columnffornnfa corresponding adjustment is invariably required of the gi'rder-forin,l to which the'narrow side-plates. arev secured by the rivets "3 7, For example, acoluinn-form adjusted to six'- teeninches, interior measurement, would for proximately .the proper length, thescrew-z jack sci-ving to adjust the supports to the-v strength-and proportion require the girder'- forms to have' an interior measurement of about ten inches in width this wouldprobably be reduced when setting the form on the tioor above, to twelveinches for the columnforms, (a reductionv of'four inches), and to lnarrow side-plates.'

In some cases, the adjustment in thewidth of the girder-forin will be the saine 'as that of vthe column-forms supportingthem; and

when this occurs, no adjustmentof the narrow sideplates 1s necessary.

""Attention is directed to the angle-bars 36.

A r which are notched at 38. to permit the. bolts 1 '35 33 and their nuts to be moved when adjusting' the forms.

Secured to the side-plates of parallel girder-iorms are supporting-bars 39 having supported thereon temporary joists'or bars .40 upon which .are to e laid planks or the like. The supporting-bars 39 and the tem poraryjoistszet() are so arranged that when -tlie planksarelaid upon the lattertheuppe lsides thereof are even with the upper edges of the side plates17 of the girder-forms.

'To adjust the girder-forms to a. perfect level and to preventsagging of the same, adjustable. supports 41 aref-provided, each of which. consists of a head or plate 42, severalpipe sect-ions 43,"and 'a screw-jack 44, The .pipe sections are interlocked with lplugs 4.5 which are' forced into one end of a pipe section aiid'entci' t-he adjacent end of theadjoining pipe sections, serving -to rigidly connect the same.` By theuse of a plurality of sections inthe formation of these' support-s, the .different fleiigths ofv sections may be used -to provide a support ,of apexact length required to leveland`v support the girder-forins. Each. of the screwjacks justably vthreaded therein,l to.which is secureda collar 48 having sockets 4 9 into.

comprises a body 46 having-a screw 47' adrwhich tlie'end of a rod or bar may Vbe insei-ted to'revolve the screw. The upper end lof this screw is smooth and enters the lower end of thelower pipe section, which 1s sup` ported on said collar. These supports may be placed at 'various points in the length of the girder-forms, and serve to' support the' latter and the concrete when cast therein.

As shown in Fig. 2, the form issupported on the foundation floor. or on a main loor cast and reinforced withr'netallic bars, and

'in the latter case reinforcingbars extend upward that-'are embedded in the columns beneath. To these bars the reinforcing bars of the columns to be cast. in the form shown are to be secured, but as any system of ref inforcing concrete may be used, I will only state that the spaces Within the several moldportions are provided with the reinforcing- 'bars and the concrete then poured into the mold spaces around said bars, the desired shape being given to the columns and girders by my improved form.:

After the column and girder-forms are filled 'and stamped,A the'tloor is formed onv the planks supported by the bars or joists 40; reinforcing barsl properly connected' with the girders previously cast are used to Vreinforce the floor..

Between the outer or wall column-forms and the girder-forms supported thereby are the wall-forms C, which are invariably of the same thickness as the girder-forms and consequently the side plates 17 of the latter are madetwider so that they extend down to the/top of the window-Openings 50, when such are below the lower: edge of the girder, as shown in Figs. 1 and 4. When casting the. first floor wall, an ornamental portion may be cast above, the water table designated 51.ii i Figs. 1 and 5. This ornamental portion is between the Jwriter table and the sill of the window-opei'iing, and the form therefor'is'adjustable to the desired height by reason of the inner and outer walls 'thereof being constructed of a plurality of plates, arranged ,to telescope.v The inner wall 52, consists of a center plate 53 and topl and bottom plates 54 having each vertical -slots 'Passing through said center plate are bolts 5G that extend through the slots 55 and have threaded on their projecting ends,

nuts 57 whereby the said plates are secured together, and wherewith adjustment to the desired height can be effected. The outer wall 58 also consists of a center plate 59 and oruaniental top and bottom plate 60. Adjiistmentan'd connection of these plates being, similar to those otthe inner wall. Be-

tween said 4wallsl are spacing-sleeves (il through which are passed bolts 02 that extend through the inner and outer walls and through suit-able retainers 63 which retain the said Walls in proper position. Bv the use .of4 different lengths 0f spacing;

sleeves, this portion' ofthe Wall-form may beadjusted to any width.

Interposed between the upper edges of said Walls and the extended'side plates of the girder-form above, are Wall-platesi secured tothe columns by angle-bars 6 5, having horizontal slots 66 therein. Adjustable on the inner side of the -Wall plate are angle-bars 6 7 Which have bolts through the slots 68 in'the Wall plates and onto which lare threaded nuts that secure To said angle-bars are secured end plates 69 having horizontal slots 70 through which extend bolts that vadjusting the angle-bars 67.
